Icenowy Zheng fd71f258bc hw/sd/allwinner-sdhost: report FIFO water level as 1 when data ready 
U-Boot queries the FIFO water level to reduce checking status register
when doing PIO SD card operation.

Report a FIFO water level of 1 when data is ready, to prevent the code
from trying to read 0 words from the FIFO each time.
